Responses to Bolden's Muslim comments reveal space community's nasty side

2010-07-07T11:50:00.008+01:00

In June NASA Administrator Charles Bolden was in Cairo, Egypt where he gave an interview to the Al Jeezera television network. Near the start of the interview, when asked why he was in Egypt, Boldin said that his goals included finding "a way to reach out to the Muslim world and engage much more with predominantly Muslim nations to help them feel good about their historic contribution to science, math, and engineering. "

This apparently polite and innocuous reply to a local audience has provoked a furious knee-jerk response from armchair astronauts (and sadly, in the case of Gene Cernan, a real astronaut). Blogs and other websites created by US space enthusiasts have included wild accusations of stupidity, cowardice, "selling out to the enemy" and other failings to Bolden. Comments on one site included stuff like

"(NASA is) being run by incompetant (sic) jackasses like Bolden and whatever MORON installed him in that position. Telling Americans that we are incapable of doing what our ancestors did, and begging for help from those who would see us destroyed, is not the job of the NASA administrator"

"Reaching out to Muslims is going to result in Muslims having access to the information to strike out on our scale. I cannot imagine anyone with a normal view of daily life who would want to provide them with that."

Few seem interested in listening to Bolden's actual words, lifting words without context from a 20 minute interview , or applying any rational analysis to them, preferring outrage to what they think he said and to direct mindless anger and spite towards Bolden (a former astronaut and combat pilot) and his boss, President Obama.

The space community ought to be a forward-looking group which celebrates education and peaceful exploration (remember "we came in peace for all mankind"?), but this unseemly fuss has revealed some ugly streaks of deliberate ignorance and prejudice in its ranks.

In advance of the landings

2010-06-23T14:50:00.007+01:00

It has been a busy week for strange things in in the sky. We get a few unresolvable queries every year but so many in a short period must mean something. It could be we're about to be invaded, an odd statistical quirk or perhaps the good weather means more people are outdoors and are looking at the sky. Here are the details followed by my comments.

Friday 18 June: a lady in Belfast observed over several minutes a slowly moving orange light which left a smoke trail and appeared to have bits dropping off it. It was recorded on video (see still above).
Saturday 19 June: a gentleman in Bangor observed a slowly drifting fireball leaving a smoke trail. It eventually vanished. The witness rang friends a few miles away who had seen it too.
Saturday 19 June: a family watching a sunset from the north coast observed a flaming comet-like object which hung in the sky for 15 minutes or more and gradually dispersed.
Monday 21 June: an observer in Cookstown observed a relatively bright but slowly moving light which abruptly "exploded", becoming extremely bright, then faded away.
Tuesday 22 June: an observer in Maghera reported a fireball like a burning aircraft which appeared to fall in a nearby field.

So what have these people seen? I was not there so I cannot say. The first two sound like the 'Chinese lanterns' so common today. I have never seen one myself but these really do seem meet the description. The 'flaming comet' is a mystery; my best guess is it was a high-altitude cloud or contrail illuminated by the reddish rays of the setting Sun. I'm fairly certain the exploding light was the flare of an Iridium satellite, a magnitude -6 one was visible from the witness's location during the time he was observing. The final one may have been a bright meteor or bolide. I hoping some else may have seen it. (Update: sadly, as of 1 July no one else has came forward to confirm this sighting.)

Alas, I am very certain none of these represent sightings of alien spacecraft. Unidentified flying objects and spaceships are not necessarily the same thing.

Mysteries of Jupiter

2010-06-18T14:09:00.007+01:00

That second most important object in the Solar System, Jupiter, has had its ups and downs recently.

Several months ago its Southern Equatorial Belt vanished. Jupiter is of course a gas giant world with no surface as we know it. When we look at Jupiter through a telescope or binoculars (what do you mean you've never seen it? Look east in the early morning sky, it's the big bright thing!) we are looking at the top of a cloudscape. The planet's rapid spin forces the clouds into a series of bands running parallel to the planet's equator. Dark coloured bands are called belts, light ones zones, each has its own characteristics and is semi-permanent. The zones' pale colours are those of frigid wisps of frozen ammonia crystals, the belts are coloured by darker (possibly organic) material dredged from the planet's mysterious depths.

The Southern Equatorial Belt is usually the most distinct and dramatic belt, unsurprisingly the Great Red Spot is to be found there. Occasionally, though it fades away leaving a pale emptiness, obscured by cold clouds of ammonia, only to emerge again. We do not know why yet, the whole planet's atmosphere is a complex system of convectional upflows and downdrafts driven by titanic interplays of heat from the Sun and Jupiter's interior shaped by the mighty Coriolis forces of the planet's spin. We cannot yet accurately model the atmosphere of a tiny world like our own, never mind that of a behemoth like Jupiter. Presumably in the next few months the Southern Equatorial Belt will reappear, until then I cannot look at Jupiter without thinking that something is missing.

Then on 3 June 2010 amateur astronomers Anthony Wesley (in Australia) and Chris Go (in the Philipines) simultaneously observed a flash of light on the disc of Jupiter. This is not Wesley's first discovery of something hitting Jupiter, he was already celebrated for drawing the world's attention to the July 2009 impact on the planet which left a black smudge almost the size of the Earth on the planet. Similar wounds were observed following the 1994 impacts of the Shoemaker-Levy 9 cometary bodies and are thought to be clouds of dark and sooty debris from the impacting body.

Yet no such marks have appeared this time. Even the Hubble Space telescope's very sensitive Wide Field Camera 3 has failed to find any Jovian bruises. The impact location is circled in the HST image above, nothing can be seen there. Why was this event's aftermath so different? The previous impactors are believed to have penetrated deep into the planet's gargantuan atmosphere before exploding. In the latest case, the object was probably a giant meteor (giant by our standard, tiny compared to the previous impacting bodies) which burnt up at a high altitude above Jupiter's cloud tops, failing to leave behind a debris cloud, as seen in previous Jupiter collisions.

Wesley and Go were lucky enough to observe a fleeting glimpse of a flash of energy bright enough to be seen here on Earth, across 770 million kilometres of space. Take a moment to imagine what a similar impact would do to our fragile world. It is a frightening thought.

One of ours

The gorgeous sight of the upper stage of SpaceX's Falcon 9 launcher spinning and venting fuel over Australia is clearly seen in this video. It seems to be getting more exposure than the launch itself.

This is something clearly identified yet it is astonishing how many people don't want reality to introduce on their speculations (alien spaceship, testing of scalar weapon, testing of torsional physics weapon, testing of HAARP, Sign of the End Times).

Watch the video, it is really a spaceship. But it's one of our's.

Nice video of this launch from JAXA's rather pretty launch site.

Good luck Akatuki!

Quite simply the absolute final proof of alien visitation

2010-05-14T12:50:00.000+01:00

I received a polite e-mail earlier this week asking for comments on the UFO observed hovering over our building. As I had missed this spectacle (and I'm sure you did too), I was glad to see that it had been photographed, so I followed the link supplied by the e-mailer.

Well, what more can I say other that I am amazed, astonished, astounded, flabbergasted, gob-smacked, staggered, stunned, thunderstruck...you get the idea. This image is quite definitely the absolute, final proof that extraterrestrial intelligence exists and is visiting us here in Armagh on planet Earth (hmm "Intelligent beings come to Armagh Planetarium", could this be a new advertising slogan?)

Anyway, the Fermi Paradox is no more. We are not alone. Call Fox Mulder, fetch Ellie Arroway, 'phone MJ12, get on the hotline to X-Com and SHADO, cry "UFO" and let slip the Men in Black!

So now SETI is finished, I have to find a new screen saver!

Yes we did!

2010-05-14T10:30:00.001+01:00

I was at the excellent talk (organised by Armagh Observatory) by Martin Hendry at St Patrick's Trian last night. Entitled "Did we really land on the Moon?", it was prompted by Dr Hendry's viewing of that lying TV programme the Fox TV network showed in 2001. In just over an hour, the ten most commonly cited arguments (no stars, waving flags, non-parallel shadows etc) from the makers of moronic DVDs and stupid books were exposed as the nonsense they are. It was a good event, although it did appear to be preaching to the converted. I doubt if there were any hardcore hoax believers in the audience.

If you missed this talk but would like to know more on this topic, Dr Hendry recommended the wonderful website www.clavius.org.

Zero-g ≠ space!

2010-02-26T10:28:00.000Z

Reading the BBC news website I saw the above story and wondered who they meant. Was one of those wonderful astronomical artists, perhaps David A. Hardy or Lynette R. Cook, packing it in? Or did they mean Alan Bean or Alexei Leonov, space pioneers and painters?

When I read the story, I learned that the artist was Nasser Azam, "who hit the headlines in 2008 when he painted in space". Azam sold the painting for £223,000 and is now planning a trip to Antarctica for a new project. I hope he has a great time.

There is one little nitpick I'd like to make: Nasser Azam has never been into space!

Azam painted his work on a flight in a Russian cargo 'plane. During its flight it manoeuvered through a series of parabolic arcs allowing brief periods of microgravity. According to the BBC it climbed as high as 23 000 feet. Space officially begins 100 km above the Earth's surface, so Azam's space adventure took place 93 km too low.

The BBC website features several stories about his career and these use statements like "since Azam returned from his trip to space", I find these disappointing, showing a dismal scientific illiteracy by such a respected institution.

The Big Questions

2010-02-24T14:36:00.000Z

So what is Armagh Planetarium? Why does this blog exist? And who is writing this?

Armagh Planetarium is the oldest functioning planetarium in the UK. Sited in the historic city of Armagh, our mission is "To advance and promote the knowledge and understanding of astronomy and related sciences" and we've been doing this since 1968 (the picture shows the planetarium building when it opened, it has changed a lot over the years). You can discover more about us by exploring the Armagh Planetarium website

This blog exists to further our mission. Although we have thousands of visitors every year and we travel throughout Ireland to introduce the public to the awe and joy of astronomy we know that there are so many others out there who we can't visit or can't visit us. We hope that we'll be able to reach out with interesting stories about the wider Universe through this blog.

I'm Colin Johnston, the Planetarium's Science Communicator and I'll be the usual blogger, but I'm sure other members of the Armagh Planetarium team will drop by from time to time.

So that's the introductions out of the way, now on with the Universe!

Welcome

2010-02-17T11:54:00.000Z

Welcome to Armagh Planetarium's Blog. Here you can find what's new and exciting at Armagh Planetarium and in astronomy, space exploration and related sciences. Please keep visiting us, there'll always something interesting happening in our wonderful Universe.

For example, on 13 February that marvellous probe Cassini flew past Saturn's moon Mimas. Above you can see an image it took during the encounter. Mimas is a ball of ice about 200 km across and the probe was just 70 000 km from it when the image was taken. You can just see giant Saturn behind it. Fantastic!
